For polyphase merge sort, there's only one output tape per phase. With 4 tape drives, the initial setup distributes runs between the 3 other drives, so after the initial distribution, it is always 3 input tapes, 1 output tape. The Fibonacci numbers only apply to a 3 tape scenario.

WebThis simple poly phase circuit consists of complementary RC subcircuits. A low-pass transfer function from the input to one output shifts the phase by -45º at the corner frequency, and a high-pass transfer function to the other output shifts the phase by +45º at the corner frequency. The net phase difference between the two outputs will be 90º. WebNext, we explain the properties of polyphase filters (i.e., they have all-pass gain and possible different phases). Each polyphase filter ρ k (n) operating at the original sampling rate f s … WebPolyphase decimation filters provide speed optimization because each polyphase filter runs at the output data rate.
